Rated 5 out of 5 by Used as a repair. Good. I used this as a temporary repair to a garage roof joining a building. At this price I used this to hold the rain out over a wet winter. Its good stuff and holds its own when using a large bead. Quite oily and sticky which is good against the rain. 25 May 2016
Rated 5 out of 5 by Excellent product As I was erecting new guttering, there was a slight mismatch to the gutter next door, so used to fill up the small void. Very easy to manipulate into place. More importantly no leaks, great product, great price. 11 May 2016
Rated 5 out of 5 by Does what it says on the tube! Brought to help re-seal joints in guttering that had been taken down from lean to and erected in a different location, was a few leaks before as using old guttering but this stuff has done the job, easy to use and would recommend for the price! 6 May 2016
Rated 5 out of 5 by Simple and easy to use Make sure the surfaces are clean and it sets quick - good for a repair 19 Apr 2016

I fixed some gutters yesterday and the sealant still hasn't set (ie, touching a finger on it still marks my finger) some 18 hours later despite it being a relatively warm day (13 degrees) and sunny.

Answer: 
Hi MikeyDee, According to the Technical Data Sheet from the Supplier the sealant does not skin. The surface of the sealant will appear dry to the touch after several days but will remain pliable beneath the surface.
Full cure normally occurs in 2 to 4 days. Rate of cure will depend on thickness, ambient temperature, joint size and design. Lower temperatures and drier conditions will result in a slower rate of cure.
I hope this information is of help to you.

I require an adhesive and weatherproof sealant for use for sticking roofing felt on a shed roof and for sealing it to prevent water penetration.

Answer: 
Hi MikePainter,

We would suggest that you use a felt adhesive for this application as although this product does have adhesive qualities it has been designed as a sealant.

Thank you for using Q and A.

Hello Madhu2015.
This does require a gun, you can use any 310ml applicator gun such as http://www.screwfix.com/p/p-c-cox-easiflow-gun/79714.
I hope this has helped
